Description

Stand der TechnikState of the art

Die Erfindung betrifft ein Gehäuseteil mit einem daran angeordneten Rastelement mit den im Oberbegriff des unabhängigen Anspruchs 1 angegebenen Merkmalen.The invention relates to a housing part with an arranged thereon Locking element with the in the preamble of the independent Claim 1 specified features.

Ein derartiges Gehäuseteil ist beispielsweise aus der DE 197 23 952 A1 bekannt. Das dort gezeigte Gehäuse eines Abspielgerätes für Aufzeichnungsträger weist an seiner Frontseite ein Rastelement aufweist, das mit einem Rasthaken von der Frontwand des Gehäuses absteht, welcher um eine parallel zu der Frontwand verlaufende Achse entgegen der Spannkraft eines Federelementes schwenkbar ist. Das Federelement wird durch eine über das Schwenkgelenk geschobene Schenkelfeder gebildet, die sich mit einem Ende an dem Rasthaken und mit dem anderen Ende an der Frontseite des Gehäuses abstützt. Derartige Rastelemente dienen beispielsweise zur Arretierung einer vor die Frontwand schwenkbaren Geräteklappe. Durch Betätigung einer in die Geräteklappe integrierten und auf den Rasthaken einwirkenden Drucktaste wird das Rastelement entgegen der Spannkraft des Federelementes bei gleichzeitiger Freigabe der Geräteklappe um seine Drehachse geschwenkt. Nachteilig bei den bekannten Anordnungen ist, daß die Montage des Rastelementes mit dem Federelement relativ aufwendig ist, da das Federelement unabhängig von dem Rastelement gefertigt werden muß und das Rastelement zusammen mit dem Federelement vom Gehäuseinnenraum aus an dem Gehäuseteil festgelegt wird. Das Federelement und das Rastelement müssen in ihren Dimensionierungen und Lage sorgfältig aufeinander abgestimmt sein, um eine einwandfreie Funktion zu gewährleisten. Ein nachträglicher Einbau des Rastelementes von außerhalb des Gehäuses ist nicht möglich.Such a housing part is for example from DE 197 23 952 A1 known. The housing of a player shown there for record carriers instructs on its front Has locking element with a locking hook from the front wall of the housing protrudes, which is parallel to the Front wall extending axis against the tension force of a spring element is pivotable. The spring element is replaced by a Leg spring pushed over the swivel joint, which one end of the locking hook and the other end supported on the front of the housing. Such locking elements serve, for example, to lock one in front of the Front wall swiveling device flap. By pressing one integrated in the device flap and acting on the locking hook Push button becomes the locking element against the clamping force of the spring element with simultaneous release of the device flap pivoted about its axis of rotation. A disadvantage of the known arrangements is that the assembly of the locking element with the spring element is relatively expensive because the spring element must be made independently of the locking element and the locking element together with the spring element from the housing interior is fixed on the housing part. The spring element and the locking element must be dimensioned and location must be carefully coordinated to ensure flawless To ensure function. A subsequent installation the locking element from outside the housing is not possible.

Darüber hinaus sind feststehende Rasthaken bekannt, die einen elastisch biegsamen von dem Gehäuseteil abstehenden Grundkörper aufweisen dessen Ende hakenförmig ausgebildet ist. Ein Schwenkgelenk ist nicht erforderlich, da der Rasthaken zur Freigabe einer schwenkbaren Frontklappe durch ein auf den Rasthaken einwirkendes Betätigungselement gebogen wird. Derartige Rasthaken neigen jedoch zur Materialermüdung, so daß der Rasthaken nach einiger Zeit nicht mehr hinter dem dafür vorgesehenen Vorsprung der Klappe einrastet und die Klappe nicht mehr zuverlässig schließt.In addition, fixed locking hooks are known, the one elastically flexible base body protruding from the housing part have the end of which is hook-shaped. On Swivel joint is not necessary because the locking hook for Release of a swiveling front flap by a on the Locking hook acting actuator is bent. Such However, locking hooks tend to material fatigue, so that after a while, the locking hook no longer behind that provided projection of the flap engages and the flap no longer closes reliably.

Vorteile der ErfindungAdvantages of the invention

    • Beschreibung eines AusführungsbeispielsDescription of an embodiment

    Fig. 1 zeigt im Querschnitt eine Teilansicht eines Gehäuseteils, beispielsweise des Gehäuses eines Autoradiogerätes. Das Gehäuse 1 umgibt einen Gehäuseinnenraum 18 der durch eine Ausnehmung 5 in einer Gehäusewand 3 mit dem Außenraum verbunden ist. Die Gehäusewand 3 ist in diesem Beispiel die Vorderwand des Radiogerätes. Eine nicht dargestellte Frontklappe kann vor die Vorderwand 3 geschwenkt werden, wobei ein Rastelement 2 vorgesehen ist, welches die Frontklappe in der geschlossenen Position an der Vorderwand 3 des Gehäuseteils 1 arretiert. Fig. 1 zeigt die Montage dieses Rastelementes an dem Gehäuseteil. Die Ausnehmung 5 weist an zwei sich gegenüberliegenden Innenwänden, von denen in der Querschnittsdarstellung von Fig. 1 nur eine erkennbar ist, jeweils eine im wesentlichen U- oder V-förmige Führungsnut 13 auf, deren offenes Ende dem Außenraum zugewandt ist und deren geschlossenes Ende in dem Gehäuseinnenraum 18 angeordnet ist und ein Lager 9 für einen Lagerzapfen 8 des Rastelementes 2 bildet. Die Führungsnut 13 ist an der Innenwandung der Ausnehmung 5 und einem Vorsprung 15 angeordnet, welcher auf der dem Gehäuseinnenraum 18 zugewandten Seite 10 von der Gehäusewand 3 absteht.1 shows in cross section a partial view of a housing part, for example the housing of a car radio. The housing 1 surrounds a housing interior 18 through a Recess 5 in a housing wall 3 connected to the outside is. The housing wall 3 is the front wall in this example of the radio. A front flap, not shown can be pivoted in front of the front wall 3, with a locking element 2 is provided, which the front flap in the closed Position on the front wall 3 of the housing part 1 locked. Fig. 1 shows the assembly of this locking element the housing part. The recess 5 faces two opposite one another Interior walls, one of which is in cross-section 1 only one can be seen, one in each essential U- or V-shaped guide groove 13, the open End facing the outside space and its closed End is arranged in the housing interior 18 and a Bearing 9 for a bearing pin 8 of the locking element 2 forms. The guide groove 13 is on the inner wall of the recess 5 and a projection 15 which is arranged on the housing interior 18 facing side 10 of the housing wall 3 protrudes.

    Das Rastelement 2 ist als Formteil aus Kunststoff gefertigt, vorzugsweise aus Poly-Oxymethylen (POM) oder einem anderen elastisch biegsamen Kunststoff und weist einen im wesentlichen quaderförmigen Grundkörper 14 auf, von dem an sich gegenüberliegenden Seitenwänden zwei Lagerzapfen 8 senkrecht abstehen, die koaxial zueinander angeordnet sind. Von dem Grundkörper 14 steht ein mit einer Rastnase 17 versehener Rasthaken 4 senkrecht zu den beiden Lagerzapfen 8 ab. An dem Grundkörper 14 ist weiterhin eine elastisch biegsame Zunge 6 ausgebildet, die ausgehend von der von dem Rasthaken 4 abgewandten Seite des Grundkörpers 14 derart gebogen ist, daß ihr freies Ende leicht schräg zu dem Rasthaken 4 von dem Grundkörper 14 absteht. An dem der Zunge 6 gegenüberliegenden Ende des Rastelementes 2 steht ein elastisch biegsames schenkelförmiges Federelement 7 senkrecht zu dem Rasthaken 4 und senkrecht zu den beiden Lagerzapfen 8 von dem Grundkörper 14 ab. Das Federelement 7 kann aber auch in einem anderen Winkel von dem Grundkörper abstehen. Das Federelement 7 weist eine Materialstärke auf, die ausreichend gering ist, um eine elastische Biegsamkeit des Federelementes 7 zu erreichen, und hat quasi die Funktion einer Blattfeder, welche eine federelastische Auslenkung des Rastelementes 2 ermöglicht.The locking element 2 is made as a molded part made of plastic, preferably made of poly-oxymethylene (POM) or another elastic pliable plastic and has one essentially cuboid base body 14, of which is opposite Side walls two trunnions 8 vertically stand out, which are arranged coaxially to each other. Of the Base body 14 is provided with a locking lug 17 Locking hooks 4 perpendicular to the two journals 8. To the Base body 14 is also an elastically flexible tongue 6 formed starting from that facing away from the locking hook 4 Side of the base body 14 is bent such that you free end slightly oblique to the locking hook 4 from the base body 14 stands out. At the end opposite the tongue 6 the locking element 2 is an elastically flexible leg-shaped Spring element 7 perpendicular to the locking hook 4 and perpendicular to the two bearing pins 8 of the base body 14 from. The spring element 7 can also at a different angle protrude from the body. The spring element 7 has one Material thickness that is sufficiently low to be elastic To achieve flexibility of the spring element 7, and has the function of a leaf spring, which is a spring elastic Deflection of the locking element 2 allows.

    Bei der Montage wird zunächst das Rastelement mit dem als Federelement vorgesehenen Schenkel 7 von außerhalb des Gehäuses 1 durch die Ausnehmung 5 in den Geräteinnenraum eingeführt und die beiden Lagerzapfen 8 in die Führungsnuten 13 in Richtung des Pfeils a in Fig. 1 eingeschoben, bis sich die Lagerzapfen 8 in den Lagerpfannen 9 befinden. Die trichterförmigen Führungsnuten 13 erleichtern hierbei das Einschieben. Anschließend wird das Rastelement 4 um die Lagerzapfen 8 in Richtung des Pfeils b zur Gehäusewand 3 geschwenkt. Der durch die Ausnehmung 5 nach außen abstehende Rasthaken 4 bildet hierbei eine Handhabe zum Halten und Schwenken des Rastelementes. Durch die Schwenkbewegung wird die elastisch biegsame Zunge 6 gegen den Rand der Ausnehmung 5 gedrückt und federt in Richtung des Pfeils c in Fig. 1 zurück. Durch weiteres Schwenken in Richtung des Pfeils b gelangt das Rastelement 2 in die in Fig. 2 gezeigte Position. Die elastisch biegsame Zunge 6 spreizt hinter dem Rand der Ausnehmung 5 in Richtung des Pfeils d auf hinterfaßt widerhakenartig den Rand der Ausnehmung 5 auf der dem Gehäuseinnenraum 18 zugewandten Seite 10 der Gehäusewand 3. Etwa zum gleichen Zeitpunkt der Schwenkbewegung gelangt das Federelement 7 an einem Anschlag 11 an der Innenseite 10 der Gehäusewand zur Anlage. Die Dimensionen des Federelementes 7 und der Zunge 6 können so aufeinander abgestimmt sein, daß das Federelement 7 an dem Anschlag 11 zur Anlage gelangt, bevor die Zunge 6 hinter dem Rand der Ausnehmung 5 aufspreizt. In diesem Fall wird das Rastelement 2 gegen die Spannkraft des Federelementes 2 noch etwas in Richtung des Pfeiles b geschwenkt, bis die Zunge 6 hinter der Ausnehmung verrastet. Hierdurch wird erreicht, daß die Zunge 6 durch die Spannkraft des Federelementes 7 gegen die Innenseite 10 der Gehäusewand vorgespannt wird. Klappergeräusche können so vermieden werden.During assembly, the locking element is first used as a spring element provided leg 7 from outside the housing 1 inserted through the recess 5 in the interior of the device and the two journals 8 in the guide grooves 13 in the direction of arrow a in Fig. 1 until the bearing pin 8 are in the bearing pans 9. The funnel-shaped Guide grooves 13 facilitate insertion. Subsequently the locking element 4 around the bearing pin 8 in Direction of arrow b pivoted to the housing wall 3. The through the recess 5 forms outwardly projecting locking hooks 4 here a handle for holding and pivoting the locking element. The pivoting movement makes the elastic pliable Tongue 6 pressed against the edge of the recess 5 and springs back in the direction of arrow c in FIG. 1. By further Swiveling in the direction of arrow b reaches the locking element 2 in the position shown in Fig. 2. The elastic pliable Tongue 6 spreads behind the edge of the recess 5 in the direction of arrow d on barbed like the barb of the edge of the recess 5 on the side facing the housing interior 18 10 the housing wall 3. At about the same time the The spring element 7 pivots at a stop 11 on the inside 10 of the housing wall to the system. The dimensions the spring element 7 and the tongue 6 can thus be on top of each other be coordinated that the spring element 7 on the stop 11 arrives before the tongue 6 behind the Edge of the recess 5 spreads. In this case, the locking element 2 against the clamping force of the spring element 2 still slightly pivoted in the direction of arrow b until the tongue 6 locked behind the recess. This ensures that the tongue 6 by the tension of the spring element 7 against the inside 10 of the housing wall is biased. Rattling noises can be avoided.

    Fig. 3 zeigt das Rastelement 2 in einem Zustand, in dem die schwenkbare Frontklappe freigegeben wird. Zu diesem Zweck ist eine nicht dargestellte Drucktaste in der Frontklappe eingebaut, welche bei einer Betätigung den Rasthaken 4 in Richtung des Pfeils e schwenkt, wodurch die hinter einem Vorsprung der nicht dargestellten Frontklappe verrastete Rastnase 17 die Frontklappe freigibt. Beim Schwenken des Rastelements 2 um die Lagerzapfen 8 wird das von dem Grundkörper 14 abstehende Ende des Federelementes 7 gegen des Vorsprung 11 derart angedrückt, daß sich das elastisch biegsame Federelement in Richtung des Pfeils f verbiegt. Das Rastelement 2 ist nun gegen den Anschlag 11 vorgespannt und bewegt sich nach Loslassen der auf den Rasthaken einwirkenden Drucktaste in die in Fig. 2 gezeigte Position zurück.Fig. 3 shows the locking element 2 in a state in which the pivoting front flap is released. For this purpose a push button, not shown, installed in the front flap, which, when actuated, the locking hook 4 in the direction of the arrow e pivots, whereby the behind a projection of the not shown front flap latched catch 17 the Front flap releases. When pivoting the locking element 2 around the bearing journal 8 will protrude from the base body 14 End of the spring element 7 pressed against the projection 11 in such a way that the elastically flexible spring element in the direction of the arrow f bends. The locking element 2 is now against the stop 11 biased and moves after releasing the pushbutton acting on the locking hook in the in Fig. 2 position shown back.
